The crane manufacturer tells you the 6 steps for the maintenance of a single beam crane

The crane manufacturer reminds you that every crane must be well maintained to extend its service life. Next, we will tell you the six steps of electric single-girder crane maintenance!

 1. Maintenance of electric single-beam crane-enough: enough oil, water, and air

  If the supply of diesel, gasoline and air is not timely or interrupted, there will be difficulties in starting, poor combustion, reduced power, and the crane engine cannot operate normally. If the oil supply is insufficient or interrupted, the engine will be poorly lubricated, the body will be severely worn, and even tile burning will occur. If the cooling water is insufficient, the temperature of the machine will be too high, the power will be reduced, the wear will increase, and the service life will be reduced.



 2. Maintenance of the electric single-beam crane-inspection: often check the fastening parts

  Due to the impact of vibration and uneven load during the use of diesel engines and gasoline engines, bolts and nuts are easy to loosen. In addition, the adjustment bolts of all parts must be checked to avoid accidents that damage the body due to loosening.

 3. Maintenance of electric single-beam crane-net: oil net, water net, gas net and body net

Diesel and gasoline are the main fuels of crane engines. If the diesel and gasoline are not pure, they will wear out the precision fitting body, increase the fitting clearance, cause oil leakage, dripping, decrease the fuel supply pressure, increase the clearance, and even cause oil passages. Clogging, shaft holding and burning of bushes and other serious faults. If the air contains a lot of dust, it will accelerate the wear of the cylinder liner, piston and piston ring. If the cooling water is not pure, the scale of the cooling system will be blocked, which will hinder the heat dissipation of the crane engine, the lubrication conditions will be poor, and the body will be severely worn. If the surface of the machine body is not clean, the surface will be corroded and the service life will be shortened.

 4. Maintenance of electric single-beam crane-use: the crane engine is used correctly

  Before driving, lubricate the lubricated parts such as bearings. After starting, wait until the water temperature reaches 40℃-50℃ before putting it into operation. Long-term overload or low-speed operation is strictly prohibited. Before stopping, remove the load and reduce the speed. After parking in winter, wait until the water temperature drops to 40°C-50°C, except for the engine that has been filled with antifreeze with cooling water. Normally, it is necessary to do the maintenance work of the engine regularly to keep the crane engine running in good condition. Observe and inspect frequently to find faults and eliminate them in time.

 5. Maintenance of electric single-beam crane-grinding: running-in

   This is the basis for prolonging the service life. Whether it is a new car or an overhauled engine, it must be run-in according to regulations before it can be put into normal operation.

 6. Maintenance of electric single beam crane-adjustment

That is to say, the valve clearance, valve phase, fuel supply advance angle, fuel injection pressure and ignition timing of diesel or gasoline engines should be checked and adjusted in time to ensure that the crane engine is always in good technical condition to save fuel and extend its use. life.
